Healthy human immune system cells can respond to HIV-1
AIDS patients' failure to clear HIV-1 might not be due to the inability of the human immune system to recognise the virus, as was previously thought. view more (2006-05-18)
Borrelia infection from a tick bite just as possible in a city centre park
The chances of getting a Borrelia infection from a tick bite are no different in a city centre park than they are out in the archipelago. This is one of the recent discoveries of Professor Matti Viljanen and his research team who are looking into how the Borrelia bacteria deceives and manipulates the human immune defence system. The research... view more... (2003-02-03)
New hope for HIV sufferers as immunosuppressant delays AIDS onset
A drug that suppresses the immune system delays the onset of AIDS in patients with HIV, according to a study published this week in BMC Medicine. Prednisolone, taken without any antiviral therapy, postponed the loss of T-cells that leads to AIDS in 50% of HIV sufferers by between 2 and 10 years. HIV leads to a complex disorder that combines an... view more... (2004-04-30)
The right messenger for a healthy immune response
Researchers from the Molecular Immunology group at the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany have now shown that Beta-Interferon also plays a crucial role during an immune response: without Beta-Interferon immune cells are unable to show "wanted posters" of pathogens to other cells. view more (2009-07-20)
Built-in molecular brakes curb the sniffles
Researchers at Johns Hopkins have discovered how our anti-infection machinery turns itself down and limits the sniffles, congestion and fevers that are a side effect of the campaign against invading viruses. view more (2007-01-18)
Reconstructed 1918 influenza virus induces immune response that fails to protect
An analysis of mice infected with the reconstructed 1918 influenza virus has revealed that although the infection triggered a very strong immune system response, the response failed to protect the animals from severe lung disease and death. view more (2006-09-28)
New technology makes clinical research more precise
The Flanders Interuniversity Institute for Biotechnology (VIB) and AlgoNomics have joined forces to develop a technology that verifies whether certain proteins induce an immune response in humans. view more (2006-12-12)
Knowledge of dendritic cells branches out
Dendritic cells (or "DC" ) are specialised white blood cells that patrol the body, searching for infections. view more (2006-05-09)
Fruit flies show how salmonella escapes immune defenses
Salmonella are wily and obnoxious bacterial invaders--escape artists capable of evading multiple immune responses and causing a harsh and debilitating intestinal infection. view more (2008-04-17)
Why doesn't the immune system attack the small intestine?
Answering one of the oldest questions in human physiology, researchers at Dana-Farber Cancer Institute have discovered why the body's immune system-perpetually on guard against foreign microbes like bacteria - doesn't attack tissues in the small intestine that harbor millions of bacteria cells. view more (2007-01-10)
Deficient regulators in the immune system responsible for type 1 diabetes
The main regulators of the immune system, called CD4+Treg cells, are thought to be highly involved in a large range of immune diseases. view more (2008-01-25)
Dysentery uses 'sword and shield' to cause infection
Scientists have found that the bacterium that causes dysentery uses a 'sword and shield' approach to cause infection. view more (2005-02-23)
Exercising our immune system
Elite athletes - often perceived as the epitome of health and fitness - may be more susceptible to common illness and are therefore proving useful in helping scientists understand more about the immune system. view more (2007-12-04)
How Toxoplasma gondii gets noticed
Researchers provide insight into how Toxoplasma gondii, a common parasite of people and other animals, triggers an immune response in its host. view more (2009-01-20)
Individuals vary their immune response according to age, sex and the costs
Is it always good to respond maximally when pathogens or disease strike, or should individuals vary their immune response to balance immediate and future costs? view more (2008-09-11)
Immune system activated in schizophrenia
Researchers at the Swedish medical university Karolinska Institutet have discovered that patients with recent-onset schizophrenia have higher levels of inflammatory substances in their brains. Their findings offer hope of being able to treat schizophrenia with drugs that affect the immune system. view more (2009-11-18)
U of MN research shows how infection-fighting cells interact
Researchers at the University of Minnesota have identified key insights into how different types of infection-fighting T-cells survive and co-exist within the body's immune system. view more (2006-03-06)
The road to allergy
A UK scientist has discovered the route and type of transport taken by peanut proteins through the gut to the immune system. This route favours an immune response, which helps explain why peanuts are one of the most allergenic foods. view more (2004-11-18)
Cancer vaccine one step closer
Andreea Ioan-Facsinay from Leiden University Medical Center has attached proteins from tumour cells to antibodies. With these she treated immune cells from a mouse. These treated cells were used to make a vaccine, which was shown to be effective in animal experiments. If the follow-up research is successful, vaccines against cancer will become... view more...

Research exposes new target for malaria drugs
The malaria parasite has waged a successful guerrilla war against the human immune system for eons, but a study in this week's Journal of Biological Chemistry has exposed one of the tricks malaria uses to hide from the immune proteins, which may aid in future drug development. view more (2008-08-05)
